Frankly this is something subject to personal opinions and will change
over time according to community shifts.

I think the main obligation of languages and runtimes is to show
consistency in their design and behavior. If somehow part of the
community wants to enforce that "casting is a bad practice" (because
IDE support or whatever valid reason in our current decade) it's ok.
But making the language behave differently for each casting scenario
actually makes it harder for userland to apply the good practices of
the moment consistently.

Yes, precisely.
